This research introduces a distributed quantum optimization algorithm that leverages superposition-based "neurons" rather than entanglement, significantly improving noise robustness and scalability for material design. By integrating high-performance computing with this novel approach, the method achieves over 50x speedups on complex problems while mitigating common issues like barren plateaus. The work demonstrates a practical pathway toward hybrid quantum-classical solvers that outperform classical deep neural networks in specific optimization domains.
Advancing Scientific Discovery and Complex Optimization through Distributed Quantum Neural Networks
arXiv:2503.00221v2 Announce Type: replace Abstract: Optimization problems are critical across various domains, yet existing quantum algorithms, despite their great potential, struggle with scalability and accuracy due to excessive reliance on entanglement. To address these limitations, we propose variational quantum optimization algorithm (VQOA), which employs an ansatz based solely on quantum superposition, where single-qubit rotation gates function analogously to neurons in classical deep neural networks. This ansatz, which can be regarded as quantum neural networks, significantly reduces circuit complexity, enhances noise robustness, mitigates Barren Plateau issues, and enables efficient partitioning for highly complex, large-scale optimization. Furthermore, we introduce distributed VQOA (DVQOA), which integrates high-performance computing with quantum computing to achieve superior performance. These features enable a significant acceleration of material optimization tasks (e.g., metamaterial design), achieving more than 50$\times$ speedup compared to state-of-the-art optimization algorithms. Beyond material design, DVQOA efficiently solves quantum chemistry problems and \textit{N}-ary $(N \geq 2)$ optimization problems involving higher-order interactions, outperforming classical deep neural networks. These advantages establish DVQOA as a highly promising and versatile solver for real-world problems, demonstrating the practical benefits of the quantum-classical approach.
